7/31 plan year for medical plan 5500 filing did not file form 5558 by 7-month due date (2/28). Filing itself will be filed as 'Final' with no Schedule A's. Employer's fiscal year is not 7/31. Filing itself will be filed by extended due date of 5/15, even though there is no extension.
Question is: Any chance the late penalty can be waived, in light of this being essentially a blank 5500? (Would not be asking this question regarding a regular ongoing 5500 that missed filing form 5558)
